摘      要：正With event-related potential technique, this study examined the temporal sequence and neural organization of number meaning processing during one-digit solution verification. Undergraduates were asked to solve one-digit comparison （Experiment 1） and subtraction （Experiment 2） problems and 1.5s later verify whether a visually-proposed one-digit solution was correct or not based on foregoing arithmetic processing. The incorrect solutions were further divided into long- and short-distance ones in the basis of numerical distance from
